An Advanced Selenium-Carbon Cathode for Rechargeable Lithium-Selenium Batteries

Selenium has been confined in the form of cyclic Se8 molecules within ordered mesoporous carbon for use as a cathode material in Li–Se batteries. An ex situ study of the Se cathode reveals conversion from cyclic Se8 molecules into chain‐like Sen molecules upon cycling. This effectively eliminates th...

Description
Summary:Selenium has been confined in the form of cyclic Se8 molecules within ordered mesoporous carbon for use as a cathode material in Li–Se batteries. An ex situ study of the Se cathode reveals conversion from cyclic Se8 molecules into chain‐like Sen molecules upon cycling. This effectively eliminates the shuttle effect of Se, resulting in superior electrochemical performance in terms of volumetric capacity density and cycling stability.
